14 1/2 x 20 - #7 Reinforced Mailer 250/Case

These reinforced mailing envelopes are crafted with laminated fiberglass strands sandwiched between kraft paper layers. This unique construction not only provides extra tensile strength but also offers superior protection against grease, water, and oil. The laminated fiberglass reinforcements safeguard the envelopes from tearing, puncturing, and abrasion. Since they are unpadded, these envelopes are a cost - effective option for mailing. They're perfect for securely sending items that don't need cushioning.

To use these reinforced mailing envelopes, simply open the flap, place your item inside, and seal it shut. These envelopes are great for sending documents, flat items, or anything that doesn't need padding. When using, make sure your item fits comfortably inside to avoid over - stuffing, which could lead to tearing. As for maintenance, store them in a dry place away from direct sunlight and moisture. This will keep the envelopes in good condition and ensure their protective qualities last.
